How to create an RPA flow for CouchDB Data in UiPath Studio

UiPath is a Robotic Process Automation (RPA) platform with rich features and an easy-to-use UI that enables non-developers to create process automation. By using UiPath Studio, you can build an RPA program just like drawing a diagram. With the CData ODBC Driver for CouchDB, users can embed CouchDB data in the workflow.

This article walks through using the CouchDB ODBC Driver in UiPath Studio to create an RPA program that accesses CouchDB data.

Configure the Connection to CouchDB

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Set the following to connect:

• Url: The Url of your instance. For example: http://localhost:5984
• User The Apache CouchDB user account used to authenticate.
• Password The Apache CouchDB password associated with the authenticating user.

Connect UiPath Studio to CouchDB Data

Now you are ready to use CouchDB data ODBC DSN in UiPath Studio with the following steps.

1. From the Start page, click Blank to create a New Project.
2. Click Manage Packages then search for and install UiPath.Database.Activities.
3. Navigate to the Activities and drop a Flowchart (Workflow -> Flowchart -> Flowchart) onto the process.
4. Drop a database Connect activity (App Integration -> Datbase -> Connect) after the Start activity.
5. Double-click the Connect activity and configure the Connection.
   1. Click the Connection Wizard
   2. Select "Microsoft ODBC Data Source"
   3. In Connection Properties, select your DSN (CData ApacheCouchDB Source) and click OK
6. To store Connection info, create a variable and bind to Output in the Properties section. Choose DatabaseConnection in Output.
   

Create an Execute Query Activity

With the connection configured, we are ready to query CouchDB data in our RPA.

1. From the Activities navigation, select Execute Query and drop it on the Flowchart.
2. Double-click the Execute Query activity and set the properties as follows:
   • ExistingDbConnection: Your Connection variable
   • Sql: SELECT statement like SELECT MovieRuntime, MovieRating FROM Movies WHERE MovieRating = 'R'
   • DataTable: Create and use a variable with the Type System.Data.DataTable

Create Write CSV Activity

With the Connection and Execute Query activities configured, we are ready to add a Write CSV activity to the Flowchart to replicate the CouchDB data.

1. From the Activities navigation, select Write CSV and drop it after the Execute Query activity.
2. Double-click the Write CSV activity and set the properties as follows:
   • FilePath: Set to a file (new or existing) on disk (i.e.: C:\UiPath[id]-data.csv
   • DataTable: Set to the DataTable variable you created earlier

Connect the Activities and Run the Flowchart

If they are not already connected, connect each Activity that you created to complete the RPA project for extracting CouchDB data and exporting it to CSV.

Click Run to extract CouchDB data and create a CSV file.
